[A novel AGAIN! LOL]
From another thread, I was reminded of mom's Hardwick brand gas stove From late 60's early 70's.
There was a waist-high broiler (in the main oven cavity)in the shape of a large "U". Broilers in this location were not very common before self-cleaners. (except perhaps in TOL models.) They were normally found in a drawer at the bottom of the stove and used the same burner tube as the oven.
The stove had pilot-lights (and was totally non-electric assist)and the broiler drew its ignition from the top-left suface burner. It was so cool! Its pilot light was not full-time. Turning the oven dial to "Broil" sent gas to the upper (broil) burner's pilot light. There was a tube that ran up to the upper left surface burner's pilot light and the flame there would "POP" and ignite the rising (from the broiler) gas. Once ignition of the broiler's pilot light was "proved" a two-way valve would divert the flow of gas from the oven burner to the broiler burner. Neither burner would light if the pilot to the oven (bake) burner was not lit and "proven" by the safety valve.
If the broiler were to go out, or if the pilot light had never ignited, the oven's (lower) bake burner would ignite. You had to check for a broiler flame...and sometimes you can see them flaming, and other times it's not so obvious.
In its day and for something totally mechanical (did not need electricity for the controls) it was very KEWL
Where did this brand "go" ? I heard that gas-self-clearners pretty much wiped out the tranditinal gas-stove manufacturers who could not afford to re-tool and go with the revised engineering.
Who made the first gas-self cleaner and when?
The issue was limiting oxygen to the oven cavity (or the food soil would burst into flames during the pyrolytic self-clenaing incineration process) while at the same time ensuring primary and secondary air/oxygen for complete combution of the gas. I think this was resolved by putting the venturi jet outside the box, and have holes of LIMITED size for secondary air to the burner tube.
I MUST be a closet novelist!!
